食管扩张术适合于食管、贲门癌术后吻合狭窄,也可用于腐蚀性灼伤之疤痕狭窄。本组对267例术后狭窄患者行扩张术1122次,57％患者获较好效果。扩张术中所见以疤痕性环形狭窄为多,占56.9％。此类病人进食困难明显,扩张后效果较好。形成狭窄之原因为吻合时缝线在同一平面所致。近期我们采用食管置入法,对预防狭窄有初步效果。穿孔及出血为扩张术之严重并发症,故对拟行扩张之病人,必须有一周内之食管造影片,以了解吻合口的狭窄程度及有无溃疡存在。对扩张后有胸腹痛者,须住院观察,必要时及早拍摄胸片及食管造影。 Esophageal dilation is suitable for esophageal and cardiac cancer after anastomotic stricture, but it can also be used for scarring of corrosive burns. This group of 267 cases of postoperative stenosis patients performed dilatation 1122 times, 57% of patients achieved better results. There was more scarring of annular stenosis seen during dilatation, accounting for 56.9%. The difficulty of eating these patients is obvious, and the effect after expansion is better. The reason for the formation of stenosis is that the sutures are caused by the same plane during the anastomosis. Recently, we used the esophageal placement method to have a preliminary effect on the prevention of stenosis. Perforation and hemorrhage are serious complications of dilatation. Therefore, patients with planned dilation must have an esophageal radiography for a week to understand the degree of anastomotic stenosis and the presence of ulcers. Patients with chest and abdominal pain after dilation must be observed in the hospital and chest radiographs and esophageal radiography should be taken as soon as possible.
